Dragonflies and their relatives are similar in structure to an ancient group, the Meganisoptera or griffinflies, from the 325 Mya Upper Carboniferous of Europe, a group that included one of the largest insects that ever lived, Meganeuropsis permiana from the Early Permian, with a wingspan around 750 mm (30 in).

Meganeura is a genus of extinct insects from the Late Carboniferous (approximately 300 million years ago). It is a member of the extinct order Meganisoptera, which are closely related to and resemble dragonflies and damselflies (with dragonflies, damselflies and meganisopterans being part of the broader group Odonatoptera).
The Odonata (dragonflies) are also a good candidate as the oldest living member of the Pterygota. Mayflies are morphologically and physiologically more basal, but the derived characteristics of dragonflies could have evolved independently in their own direction for a long time. It seems that orders with aquatic nymphs or larvae become ...
Meganisoptera is an extinct order of large dragonfly-like insects, informally known as griffenflies or (incorrectly) as giant dragonflies. The order was formerly named Protodonata , the "proto-Odonata", for their similar appearance and supposed relation to modern Odonata ( damselflies and dragonflies ).
The emperor dragonfly is a large and bulky species. It is 73–82 mm (2.9–3.2 in) long, with average being 78 mm (3.1 in) and males growing larger than females.
In China, dragonflies have long been considered good luck, and this belief has spread to the United States. Especially if one lands on you, it means better times are ahead, according to Serafice.
Dragonflies are considered some of the earliest winged insects dating back over 300 million years ago, before dinosaurs, experts say. Warmer weather means more critters Georgia has 47 species of ...
